Let's say I have an app that takes full advantage of multi threading.
So then, for example, if I have a 3.0 GHz Duo Core do I have 6 GHz of processing power or do I have two 1.5 GHz processors running?

You would potentially posses 6 GHz of power. That, of course, depends on how well the application is coded.

If you have a 3.0 Ghz core 2 duo, then you have two cores, each running at 3.0 Ghz. If you have a 2.4 Ghz Core 2 Quad, then you have 4 x 2.4 Ghz cores running. Note that running a 3.0 Ghz dual core not going to be twice as fast as a single core because you use processing power in coordinating the workload between the two processors, etc. It depends on the application type. The speed will be significantly more, but often still nowhere close to twice as fast. Plus, you have other hardware that may be waited on, such as a graphics cart, etc. So you will get a significant performance boost, but you won't get double the performance when playing a multi-threaded game, for instance.

You have 2 3.0 GHz processors.
They each run at 3.0 GHz so it would probably be more correct to say that it is the equivalent of about a 6 GHz single core (though not quite since the multi-threading has an overhead that means dual core won't give you twice the performance).

They each run at 3.0 ghz.
But just because you have 2 3.0ghz cores, does not mean that you have 6.0 ghz processing power.
Each core can process the data at 3.0ghz, so technically since you have two cores, you can process twice the amount of data in half the time, but that is not the same as having a 6.0ghz processer.

Its two processors running each at 3.0 Ghz. Same with Quad, the amount of cores multiply the speed, but they tell you the speed each core has.

you have two processors running at 3.0 GHz.

in theory 6 ... but i seriously doubt the software can utilize the 6. the dual core and quad core are beneficial when running background programs (security software, etc.) and using an extensive application.

It depends on a lot of variations, but you still only have 3GHz of processing power as a good OS will do pre-emptive multi tasking.
